Faradaic rectification study of the metal/metal ion reactions

The kinetic parameters for Ag⁺/Ag and Cu²⁺/Cu reactions at the equilibrium potential and in the absence of dc polarisation have been obtained using the faradaic rectification method at audio frequencies. The values of transfer coefficients, ion exchange current densities and apparent rate constants, obtained for the two reactions at 27°C using 1·0mM of each of the Ag⁺ and Cu²⁺ in 1·0M KNO₃, are respectively 0·22; 7·3mA/cm²; 3·6·10^?3 cm/s and 0·45; 10·7 mA/cm²; 1·1×10^?4cm/s. These data are comparable to those reported in the literature. For obtaining reliable and reproducible results for the studies with metal/metal ion reactions suitable experimental conditions have been described.
